The 30-year-old tattoo artist and reality star confirmed the break up on her Twitter page, writing on November 10, "Man, I sure was wrong. But at least he made it a no-brainer to break that off. #lessonlearned."

"Clarification: Deadmau5 and I are no longer together," she continued, adding, "Now, we can get all of the 'I told you so's' outta the way... And move on."

DeadMau5, a 31-year-old Canadian DJ who performs wearing a giant cat head, also opened up about the split on his Facebook writing, "going to spend a little while screwing my head back on. i guess im not cut out for relationships right now. and that's all i really wan't [sic]to dwell on it right now. ill figure it out. no hard feelings."

He later added on his official Twitter account, "it happened too fast, i lost my balance and fell into a familiar dark place that im having difficulty with. she deserves someone stronger."

Von D and DeadMau5, whose real name is Joel Zimmerman, first confirmed their relationship in September. The pair began dating after meeting at a party.

Kat Von D was previously engaged to Jesse James, ex-husband of Sandra Bullock. He and Bullock, his third wife, divorced in 2010 after he admitted in interviews he was unfaithful during their almost 5-year marriage.
